Abstract

resumo patente de invenção: "bomba de pistão para um dispositivo de limpeza a alta pressão". a presente invenção refere-se a uma bomba de pistão para um aparelho de limpeza a alta pressão, com vários pistões (18) móveis em vaivém, que imergem respectivamente em uma câmara de bombeamento (52) e são retidos deslocáveis em uma parte-guia de pistão (22). a parte-guia de pistão (22) apresenta uma parede de suporte (26), na qual estão dispostos vários elementos-guia (24), que guiam respectivamente um pistão (18). para poder produzir a bomba de pistão a baixo custo, a parede de suporte (26) é executada abaulada.patent summary: "piston pump for a high pressure cleaning device". The present invention relates to a piston pump for a high pressure cleaning apparatus having several reciprocating movable pistons (18) which immerse respectively in a pumping chamber (52) and are detachable retained in a guide part of piston (22). the piston guide part (22) has a support wall (26) in which several guide elements (24) are arranged guiding a piston (18) respectively. In order to be able to produce the piston pump at low cost, the support wall (26) is made bulged.
